Eufy cameras claim to be local only, but upload data to the cloud. The company is basically lying to reporters, despite being shown evidence to the contrary. The company’s behavior is so egregious that ReviewGeek is no longer recommending them. This will be interesting to watch. If Eufy can ignore security researchers and the press … Read More “Security Vulnerabilities in Eufy Cameras” »
This is new: Newly revealed research shows that a number of major car brands, including Honda, Nissan, Infiniti, and Acura, were affected by a previously undisclosed security bug that would have allowed a savvy hacker to hijack vehicles and steal user data. According to researchers, the bug was in the car’s Sirius XM telematics infrastructure … Read More “Sirius XM Software Vulnerability” »
Twitter is having intermittent problems with its two-factor authentication system: Not all users are having problems receiving SMS authentication codes, and those who rely on an authenticator app or physical authentication token to secure their Twitter account may not have reason to test the mechanism. But users have been self-reporting issues on Twitter since the … Read More “Failures in Twitter’s Two-Factor Authentication System” »
There are no details yet, but it’s really important that you patch Open SSL 3.x when the new version comes out on Tuesday. How bad is “Critical”? According to OpenSSL, an issue of critical severity affects common configurations and is also likely exploitable. It’s likely to be abused to disclose server memory contents, and potentially … Read More “Critical Vulnerability in Open SSL” »
Nice work: Radio relay attacks are technically complicated to execute, but conceptually easy to understand: attackers simply extend the range of your existing key using what is essentially a high-tech walkie-talkie. One thief stands near you while you’re in the grocery store, intercepting your key’s transmitted signal with a radio transceiver. Another stands near your … Read More “Relay Attack against Teslas” »
This vulnerability was reported to Zoom last December: The exploit works by targeting the installer for the Zoom application, which needs to run with special user permissions in order to install or remove the main Zoom application from a computer. Though the installer requires a user to enter their password on first adding the application … Read More “Zoom Exploit on MacOS” »
I haven’t written about Apple’s Lockdown Mode yet, mostly because I haven’t delved into the details. This is how Apple describes it: Lockdown Mode offers an extreme, optional level of security for the very few users who, because of who they are or what they do, may be personally targeted by some of the most … Read More “Apple’s Lockdown Mode” »
This is a dangerous vulnerability: An assessment from security firm BitSight found six vulnerabilities in the Micodus MV720, a GPS tracker that sells for about $20 and is widely available. The researchers who performed the assessment believe the same critical vulnerabilities are present in other Micodus tracker models. The China-based manufacturer says 1.5 million of … Read More “Critical Vulnerabilities in GPS Trackers” »
This is a new vulnerability against Apple’s M1 chip. Researchers say that it is unpatchable. Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory, however, have created a novel hardware attack, which combines memory corruption and speculative execution attacks to sidestep the security feature. The attack shows that pointer authentication can be defeated without leaving … Read More “M1 Chip Vulnerability” »
Following a recent Supreme Court ruling, the Justice Department will no longer prosecute “good faith” security researchers with cybercrimes: The policy for the first time directs that good-faith security research should not be charged. Good faith security research means accessing a computer solely for purposes of good-faith testing, investigation, and/or correction of a security flaw … Read More “The Justice Department Will No Longer Charge Security Researchers with Criminal Hacking” »
